856 - ASN SALES & DISTRIBUTION INBOUND IDOC

Hi SAP SD GURUS,

There is one requirement from my client, about EDI 856 - ASN Signal INBOUND IDoc. I don't know how to configure this in SAP end.

The process is we have warehouse and the warehouse is sending the 945 Shipping Confirmation to SEEBURGER and SEEBURGER send the EDI 945 to SPS Commerce and SPS Commerce converts EDI 945 to EDI 856 and send the information to respective business partner.

New Requirement is :

Warehouse will send the signal EDI 856 - ASN to SEEBURGER and SEEBURGER will send the 2 files EDI 856 - ASN to SPS COMMERCE and SAP SYSTEM as an INBOUND IDOC.

SO to map the INBOUND IDOC for 856 ASN, I need to know the configuration, like message type, basic type and other details.

Additionally, How can I proceed this regarding mapping document.

Kindly provide some guidelines on same.

Note: I tried to find on SCN and other site but unable to get the exact requirement details.

Thanks in Advance !!!

Regards,

Kundan
